Patent GB-2093179-A (GB)
Title: Measuring opacity and detecting holes in sheet
IPC: G07D7/182
Filed: 1981-02-17
Abstract: For detecting the presence of holes or tears in a sheet (for example a banknote) and for measuring the opacity of the sheet, an area (A) of the sheet is illuminated by a source (S), a lens (L2) focuses undeflected, parallel light from the whole of this area onto a photocell (P1) to indicate the presence of holes or tears within the illuminated area, light diverging from the illuminated area passes through the said lens, through a transparent plate (TP) on which the first photocell (P1) is mounted and is then focused by a further lens (L3) onto a second photocell or matrix of photocells (P2) to measure the opacity of the area (A) of the sheet. Lenses L2 and L3 together form an image of the area (A) at P2; lenses L1 and L2 form an image of the light source (S) at P1. These two imaging systems are independent, and the advantage is that the measurement of opacity and the detection of holes or tears are therefore performed independently. <IMAGE>

Title: Reflective road studs
IPC: E01F9/06
Filed: 1981-03-17
Abstract: The above-the-road housing portion 21 of a reflective road stud has a spherical contour rising gradually from the road in all directions and provides metal shoulders defining a divergent overturning light channel for retroreflectors 35. Bridges 45, 46 across the channel, from shoulder to shoulder protect the reflective lenses 34, from tyres and lift narrow two wheel vehicle tires up and over the lenses.

Bases for the reflectors can be surface mounted, imbedded for new road construction, or anchored by bolts in a shallow recess. A removable model has a permanently secured base below road level with a detachable upper housing locked in place by a metal wedge. <IMAGE>

Title: Receptacles producing surface bubble patterns
Inventor: SWEID DR STEVEN M
IPC: A47G19/22
Filed: 1983-03-10
Abstract: Attractive bubble patterns (1) are produced at the surface of fizzy drinks (2), through bubble generating sites (3) having the shape of the pattern to be produced, and which are located at the base of the receptacle containing the drink. In glass receptacles, the bubble generating pattern could be easily produced, by, for instance, a fine engraving into the glass in the shape of the desired pattern. In soft receptacles, such as paper, other alternative techniques are used. Many geometrical shapes, such as symbols, or logos, could be produced as surface bubble patterns, provided the pattern is simple and has the appropriate dimensions. The receptacles, such as cups or glasses, producing the surface bubble patterns are used as curiosity and promotional items, and are particularly effective with fizzy dark drinks and sparkling wines. <IMAGE>
